1 answer:
X = soft tacos
y = double deckers
Dory:
3x + 3y = 11.25
Nemo:
4x + 2y = 10.00
---Now to solve for x and y---
---We find LCM of either x or y then make them cancel each other---
Dory multiply by 2:
6x + 6y = 22.50
Nemo multiply by 3:
12x + 6y = 30.00
--eliminate y---
Nemo subtract Dory:
6x = 7.50
Therefore x = 7.50 <em />÷ 6 = 1.25
---Now substitute x = 1.25 in either equation.---
Dory:
3.75 + 3y = 11.25
Therefore 3y = 11.25 - 3.75
therefore 3y = 7.50
there fore y = 2.50
y = 2.50 , x = 1.25
Sorry, that this is so long, I hope you understand. This is called simultaneous equations, you can read up on it.

Answer:
y > 6 or y < -3
Step-by-step explanation:
y² - 3y > 18
Complete the square.
y² - 3y + 9/4 > 18 + 9/4
y² - 3y + 9/4 > 81/4
(y - 3/2)² > 81/4
y - 3/2 > 9/2, or y - 3/2 < -9/2
y > 6 or y < -3
I want points!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
3 + 5 = 8 so there are 8 cards total.
3/8 are basketball and 5/8 are baseball
3/8 + 5/8 = 8/8 or 1
86
Mark brainliest please
Hope this helps you
